Nice, but why is this a warlock card? What kind of warlock deck is gonna need this card especially? The smaller Tar elemental is neutral and the bigger one is Warrior, both makes sense, but a warlock has no use of this card.

It's hard to say what's viable and what isn't yet. Let's wait until the new expansion to make hard judgements on such flexible archetypes as reno decks.

That said, of all the Kabal classes, Warlock had by far the most synergy with Reno Jackson himself. Knowing you had a heal in the works let you use Life Tap without worry, and enabled the use of otherwise too self-destructive cards like Felfire Potion. Without Reno, Renolock will suffer, and suffer in a huge way.

yeah, dudei know, that there is a thing called wildbut there should be also (good) options for standard as well

the only standard have is kill demon for 5 hp , that could work very well with imp implosion , but in standard you still can use old good card that people didn't use it much , its Imp Master generate easy imp and really useful you can even next turn play Ravenous Pterrordax to make good combo with him , plusImp Master work as taunt so enemy want always have to kill him and ignore your other minions because she will keep give you value as long she still alive
